'LOOSE-LEAF BINDER.

Application filed March 12, 1921.

Leaf Binders, of which the following is a specification.

This invention relates to loose leaf binders and has for one object to provide a binder adjustable. for different sized periorated sheets or for sheets having perforations different distances apart or ditterently located therein.

The loose leat' binders ordinarily in use have the great disadvantage, that the posts which hold the leaves are. usually secured against longitudinal displacement on the binder member, and could be used only for perforations a certain distance apart. This is a great disadvantage and makes it impossible to use similar binders with perforated sheets of differentsizes and having the` holes different spaces apart.

The present invention overcomes these disadvantages.

Another object ot the invention is to provide a binder as above described in which all the binderposts of one binder member may be. locked'by a single movement.

Another object ot the invention is to provide an economically manufactured, easily operated sectional binder post, the sect-ions of which may very quickly be assembled and disassembled for adjusting' the length of the posts for ditte-rentnumbers of leaves.

The loose leaf binder posts hitherto employed, which are adjustablel in length have the great disadvantage, that the posts are usually rigidly secured together by threaded connections. Such iittings are costly and require a long time to manipulate.

The present invention overcomes this disadvantage.

Other objects ot the invention will appear as the description proceeds; and while herein minute details of the invention are Serial No. 451,794.

described, the invention is not 'limited to these, since many and various changes may be made without departing `from the scope ot the invention as claimed.

ln the accompanying drawing showing by way of example several ot many possible embodiments of the invention,

Fig. 2 is a longitudinal section of the upper binder member;

Fig. 3 is a cross section of the binder with the covers broken away;

Fig. 4L is a longitudinal sect-ion ot' a modified form ot' lower binder member;

Fig. 5 is a cross section similar to Fig. 3, of a binder embodying the member of Fig. 4;

Fig. 6 is a side elevation partly inlongitudinal sec-tion of a` form ot' binder post;

Fig. 7 is an enlarged ragmental section of the same; and;

Fig. 8 is a side elevation of the post.

The form of our improved loose leaf binder shown in Figs. 1, 2 and 8, comprises an upper binder member 10 (Fig. 1), a lower binder member 11 and cove-r boards 12 hingedly secured to said members l() and 11 respectively. Loose leaves 15 (Fig. are disposed between said members respectively and the associated cover boards and provided with perforations 16 oi' notches at the 'inner edge portion. Blocks 17 and 18 slidable in said members l0 and 11 respectively are provided with openings 19 and 2O adapted, when the blocks are slid, to register with certain ot said pert'orat-ions 16 or notches and to receive posts 22 disposed in said openings 19 and 20 and perforations 16 or notches and secured in the openings.

The upper binder member 10 comprises upper and lower parallel spaced walls 23 and 24: respectively provided with registering post-receiving slots 25 Fig. 1) extending longitudinally of the member. The locking blocks 17 slidable therein are each provided with a longitudinal rod-receiving bore Q6 approximately tangentially intersacted by said locking bore. Bearing blocks 29 in lili! Y vided with a longitudinal rod-receiving bore 36 and at its middle part with the vertical post-receiving locking Vopening 2O approxi-Y mately tangentially intersecting with rodreceiving bore and approximately registering with said slots 36 but slightly smallerv in diameter than said first-named looking openings 19. Saidlower member also carries bearing blocks 28 in opposite ends thereof provided with alined bearing apertures disposed longitudinally of the binder member similar to the bearing apertures 29.y A

, locking rod-40 (Fig. 3) rotatable in said bearing apertureshas a squared key-receiving end 31 (Fig. 1) and has its intermediate part engaging in said bores and provided with a flat side 43 similar to the flat side 33. The posts 22 disposed in said retaining openings 19 and 20, pass through said slots and locking openings and are substantially disengaged from said locking rods when the flat sides 33 and 43 are turned toward the posts, but when the flat side is turned awa-y from the posts, the roundside ot the lower locking rod engages the post shanks 44 secured to or associated with the'blocks 18 in any suitable manner such as being riveted in the opening 2O and holds the blocks 18 against longitudinal displacement, while the upper rod 30 when turned with the round side to the post locks the post in the opening 19 and also holds the upper block17 against longitudinal displacement. Y

Y lVhile any form of binding post may be used, a sectional binding post as shown in Figs. 6 tol 8 is preferred. This post consists of a lowersection 45, having shanks 44 and 46, and one or more upper' sections 47, each, except the top section, having a reduced shank similar to the shank 46 and having at its bottom end a shank-receiving bore 48 having at its inner end a small aperture extension 49. .Said bore forms side walls 50 provided on opposite sides with bayonet slots 52V each turned ,in the same direction for forming undercut recesses having backwardly disposed recessed seats 54 on diametrically opposite sides of said wall. A diametric pin 55 in the shank 46 has both ends projecting and adapted to pass through said bayonet slots 52 of an adjacent section and tov rest in said seats 54. A helical spring 56 in the bottom of each bore 48 has an axial extension 57 litted tightly in said extension 49, said spring being compressible by the shank 46 in said bore and yieldably pressing on the shank to hold said projecting ends o't the pin in said seats. Y

)d ith the same upper binder member 10 we may use either the lower binder member 11 or11a (Figs. 4 and 5). j

The lower binder member 11a is similar to the binder member 11, comprising upper and lower parallel spaced walls, the upper 'wall only being provided with post-receiving slots 35. The retaining blocks 58 slidably disposed iny said lower binder member are eachV provided with a vertical postreceiving opening 60 spaced Vfrom a threaded longitudinal rod-receiving -bore 66 and approximately registering with said respec-` tive slots 35. Bearing blocks 2.8 in opposite ends of said binder member are provided with alined bearing apertures 29 disposed longitudinally of the 'binder member. An intermediately threaded adjusting rod 70 having a squared key-receiving end 71, and smooth end portions 72 Vengaged in said apertures 29, has intermediate right and left threads 73 engaging in said threaded bores 66. The posts 75 are secured toor associated with the blocks 58 such as by being riveted in said openings 60'and pass through said slots 35 and locking openings 19 and are locked by said locking rod 3() asexplained. The rod 70 does not engage'the posts; but rotation of the rod 70 moves the blocks 58 in oppositedirections, and thusV i spaces them different distances apart, Fig.V 5 shows a binding post 75 having a threaded connection 76 for an extension section; it is understood that either form of post section 75 or 45 may be used with either binder member.V

The operation of the device is very simple.

vThe blocks 18 with their posts, being unlocked by turning the flat sider43 to the shank 44, are slid to receive the desired perforations "of the sheet. The sheet is then moved to the desired location of the binderV and the blocks 18 locked by rotation of the 55 through the slots 52 to the seats 54.

It sets of small V'leaves are tov be used in the same plane with the upperl edge of one adjacent to the lower edge of the other, ad-

115 rod 40 with a key. The blocks 17 are then ditional posts 22 and blocks 17 and 1S will be required in orderthat each set of leaves may have two posts.

VBv the use of three posts and sheets shorter than the binder members, the sheets may be oil-.set in the well known manner of ledger posting.

`IVith the device oi Figs. 4 and 5, the blocks 58 and their posts are adjusted to receive the required perforations of the leaves by rotating` the rod 7 0, but in this case the posts each are thereby arranged equal distance from the mid point of the binder member ll, In this case, the upper binder member is applied and locked as above described.
